|Croesus is famous for introducing the world's first pure gold and pure silver coins. Prior to this, coins were produced in electrum, a naturally occurring alloy of gold and silver. Scholars argue that the gold standard of Croesus was introduced in stages, designed to recall the circulating electrum staters. Once a sufficient number had been recalled, the new light stater appeared.|
Though the light stater was produced for a longer period than the heavy stater, the light stater is actually the rarer coin.
